Sansevieria plant named ‘Tyler’

ABSTRACT

The variety ‘Tyler’ belongs to the compact  Sansevierias  group, with a height of 40 cm, and an average of 7 leaves per plant. The plant shape is an inverted triangle shape and the arrangement of the leaves is in the form of a rosette. Shows vivid green color in the center of the blades alternating with light yellowish green broad bands and narrow brilliant yellowish green margins. One remarkable trait of ‘Tyler’ is the flower, which shows downwards curved petals.

Latin name of the genus and species of the claimed plant: Sansevieriatrifasciata.

Variety denomination: Tyler.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofSansevieria plant, botanically known as Sansevieria trifasciata, of thefamily Ruscaceae, hereinafter referred to by the cultivar name “Tyler”.

Sansevieria is a monocotyledonous and succulent flowering plant, whichcan be produced in either hard-leafed or soft-leafed varieties. forinterior use as a house plant or outdoor as an ornamental plant.

The new Sansevieria ‘Tyler’ originated from a naturally-occurringmutation of the Sansevieria variety ‘Robusta’ (unpatented). The newSansevieria variety ‘Tyler’ was discovered and selected by the inventor,Marvin Gonzalez Villegas, as a single sprouting rare plant in a‘Robusta’ plantation, a controlled environment, in 2007 in Monterrey,San Carlos, province Alajuela, Costa Rica.

Asexual reproduction of the new Sansevieria cultivar by vegetativecuttings was first performed in January 2008 in Monterrey, San Carlos,Alajuela, and has demonstrated that the combination of characteristicsas herein disclosed for the new cultivar are firmly fixed and retainedthrough successive generations of asexual reproduction. The new cultivarreproduces true to type.

BRIEF SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined tobe unique characteristics of ‘Tyler’, which in combination distinguishthis Sansevieria as a new and distinct cultivar:

-   -   1. Green vivid coloration (RHS 134A) in the interior of the leaf        blade with light yellowish green (RHS 141C) margins in both        sides of the leaf (4-5 mm).    -   2. Wide, long lanceolated leaves supported in a rosette.    -   3. 40-45 cm plant height.    -   4. Erect plant habit.    -   5. Needs little water and is very drought tolerant.

The new variety ‘Tyler’ is considered a variety of Sansevieria in thegroup known as “compact Sansevieria plants”. The claimed variety ‘Tyler’presents an average of 6-7 leaves per plant when it reaches its maturity(between 7-8 months). The claimed variety ‘Tyler’ has an erect growthhabit and the entire plant can reach a height range between 40-45 cm.The leaves are wide (8.5 cm average measured at the widest part of themature leaf) and lanceolated, with a soft waxy texture and the bladesare thin and slightly wavy. The plant has an inverted triangle shape.The younger leaves show a green vivid coloration (RHS 134A) in theinterior of the leaf blade. This area shows also irregular streaks orlight yellowish-green bands (RHS 145D). There are margins in both sidesof the leaf (4-5 mm) which are light yellowish green (RHS 141C). Whenthe leaf is mature the deep color inside turns strong yellowish green(RHS 141), while margins alternate brilliant yellowish green (RHS 154B)and light yellowish-green (RHS 145C) colors. The claimed variety ismoderately drought tolerant and adapts to conditions of light and shade(interior and exterior).

The variety ‘Robusta’ gave rise to the variety ‘Tyler’. The ‘Robusta’variety is also considered part of the “compact Sansevierias” group.‘Tyler’ shows more vigor than ‘Robusta’ but has an equal number ofleaves per plant (6-7), with an average width of 8.5 cm (measured in themiddle of the mature leaf).

Plants of the new Sansevieria ‘Tyler’ differ from plants of the parentalcultivar, ‘Robusta’ (unpatented) in the characteristics described inTable 1.

Of the many commercial cultivars known to the present inventor, the mostsimilar in comparison to the new Sansevieria ‘Tyler’ is the parentalvariety ‘Robusta’ (unpatented).

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

DETAILED BOTANICAL DESCRIPTION

The new Sansevieria ‘Tyler’ has not been observed under all possibleenvironmental conditions. The phenotype of the new cultivar may varywith variations in environment such as temperature, light intensity, andday length without any change in the genotype of the plant.

The aforementioned photographs, together with the followingobservations, measurements and values describe the new Sansevieriacultivar ‘Tyler’ as grown in an open field at Monterrey, San Carlos deAlajuela province, Costa Rica, conditions which closely approximatethose generally used in commercial practice. Average temperature atMonterrey is 24.5° C. during the day and 18° C. at night. Plants growunder natural light conditions.

This crop does not require constant fertilization, to increaseproduction per area about 200 kg ha⁻¹ N, 150 kg ha⁻¹ of P and 100 kgha⁻¹ K are required, the production is closely related with soilconditions in which they are grown.

Color references are made to The Royal Horticultural Society ColourChart (R.H.S.), (April 2009) except where general colors of ordinarysignificance are used. The photographs and descriptions were takenduring the rainy season in Monterrey, San Carlos, Alajuela province,Costa Rica when outdoor day temperature was 23° C. The age of the plantsdescribed is 8 months.
